Went to tescos the other day and i saw a cat tunnel.Its got balls hanging from the inside,even thought it was for a cat,mollie is only 12 weeks so she could use it.She loves it,runs threw it and its got gaps in she can stick her head out when shes inside.Its so funny lol.And at £3 its a bargain.Thought id let you know if you have a pup it would be great fun for them xxx
